DISPOSABLE WATER CLOSET BOWL LINERS Filed Dec. 6, 1963 7714M WALINVENTOR.

United States Patent Filed Dec. 6, 1963, Ser. No. 328,543 4 Claims. (Cl.4-4) My present invention relates to a disposable water closet bowlliner, the basic primary purpose of which is to protect the exposedsurface of the interior walls of the water closet bowl covered by itfrom direct contact and soilage by fecal matter or other foreignmaterial or extraneous matter, thereby affording greater sanitation andease of cleaning; further benefits and advantages, if desired, beingobtainable by the impregnation of the material of said liner withdeodorant properties and/or antiseptic properties 'and/ or bleachingproperties The embodiment of the liner consists of a sheet of paper,cellulose, plastic or other suitable material either impregnated or notimpregnated with deodorant properties and/ or antiseptic properties and/or bleaching properties which is disposable by the flushing action ofthe water closet and sequentially dispersable and decomposable by septicsewage action, of diverse shapes to fit neatly on the desired surface ofthe inner walls of the water closet bowl, each of these diverse shapesor designs having if desired, though not shown in the accompanyingdrawing, suflicient elongation of the front of the liner to extendupward and over the front center section of the toilet seat, coveringsaid front center section, two examples of the diverse shapes orconfigurations being illustrated in the accompanying drawing.

The design of example (a) consists of a straight horizontal base and twoconvex arcs rising one at each end of the base and following thecurvilinear contour of the upper border of the side and front walls ofthe water closet bowl and meeting at the vertex of the are formed bytheir course; the design of example (b) consists of a truncatedtriangle.

The drawing is a plan view showing by solid lines the two examples ofdesigns (a) and (b) and below these two figures a cross-sectional viewof the liner in place in the water closet bowl.

Using design example (b) as illustration, the proper position of theliner in place on the inner walls of the bowl is that of the twoparallel ends of the liner lying crosswise of the bowl, the shorter endat the upper border Patented Apr. 6, 1965 of the front wall and theopposite longer end extending from the upper border of one side walldown that wall, across the lower section of the front wall and up the opposite side wall to the upper border of said opposite side wall.

It will be apparent that when in place in the water closet bowl theliner receives material deposited in the bowl, protecting the walls ofthe bowl covered by it from this direct contact, and upon the flushingaction of the water closet is itself flushed down the drain, carryingthe said deposited matter with it.

I claim as my invention:

1. A disposable water closet bowl liner comprising a sheet of materialdisposable by the flushing action of a water closet and sequentiallydispersable and decomposable by septic sewage action, said liner beingof such configuration and flexibility as to readily accommodate theinterior surface wall of said closet bowl to thereby cover and protectsaid interior surface of said water closet bowl, said liner furthercharacterized by a straight horizontal base and two convex arcs risingone at each end of the base and following the curvilinear contour of theupper border of the side and front walls of said water closet bowl andthereby meeting at the vertex of the are formed by their course.

2. A disposable closet bowl liner as defined in claim 1 wherein thefront of said liner is of such elongation as to extend upward and overthe front center section of the associated toilet seat.

3. A disposable water closet bowl liner as defined in claim 2 whereinsaid sheet of material is comprised of cellulose. m

4. A disposable water closet bowl liner as defined in claim 1impregnated with a deodorant, an anti-septic and a bleaching agent.
